MEANS FOR HEATING AND MELTING.

SPECIFICATION forming part of Letters Patent No. 787,356, dated April18, 1905.

Application filed February 16, 1904. Serial No. 193,865.

Be it known that we, JOHN (.oLLtNs and ,Ionx Fiziuacv. citizens of theUnited States, residing in Paterson, in the county of Iassaic and Stateof New Jersey, have invented certain new and useful Improvements inMeans for Ileating and Melting; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which itappertains to make anduse the same, re ference being had to the aecom ranyingdrawings. and toletters of reference marked thereon, which form a part of thisspecification.

This invention has for its object to provide means for preventing waterfrom freezing and for removingic'e which forms in or around waterpipes.A practical. easily-installed, and ILtlllIl \'-l01)zllltll expedientsuch as this is needed. for instance, in connection with the pipescalled leaders. employed forcarrying oil water from the roofs ofbuildings where in cold weather the ice or snow on the roof of abuilding melts from the heat within and, turning to water, constantlyfreezes as it slowly trickles down the leader until a mass is formedwhich ultimately clogs the pipe and sometimes bursts it.

Our invention consists in certain improvements in such apparatus lookingtoward making the same economical. easily installed, and readilyrepaired.

The invention is illustrated in the accompanying drawings in thesingleadaptation thereof above alluded to; but it will of course be understoodthat it has many other applicalions.

In the accompanying drawings, Figure l is a view illustrating ourinvention in ctmnection with the leader of a building, the view beingpartly in section and partly in elevation; and Fig. '3 is an enlargedvertical sectional view showing a part of what is illustrated in Fig. 1.

In said drawings, u designates a building having the usual roof-gutterband a sectional leader mexteuding down from the roof-gutter and adaptedto be connected at the bottom in the usual manner with a sewer or'otheroutlet. This leader is protected at the top by a strainer or other formof perforated cowl (I for preventing leaves and other obstructions fromentering the leader.

Into the leader c is extended the conductor 0 for a heat-carryingmedium. In the adaptation shown this consists of piping, which is led inpreferably near the bottom portion of the loader and extends up to thetop and then back again, being connected at its ends with asteamgenerator In Fig. 2 we show in detail the preferable manner ofassembling the leader w and the system of piping r. The section /1 ofthe leader, through the wall of which the system of piping enters, isenlarged to form a chamber and this chamber is formed at diametricallyopposite points with threaded openingsj, into which are fittedscrew-plugs A' The screw-pluglhas threaded holes m tapped through it,into which from one side are screwed the portions of the system fleading into the building to the generator and from the other side theportions 11 of said system, which latter are connected with the verticalportion or loop 1) of the system by elbows p.

The screw-plug is provided so that access may be had to the interior ofthe leader for the purpose of clearing the same of such obstructions asmay find their way into the leader and lodge where the system of pipingpasses out of the leader or elsewhere.

It is preferable to construct the system of piping-e in sections, sothat it may be built up to any height-that is to say, approximating thatof the leader.

Having thus fully described ourinvention, what we claim as new, anddesire to secure by Letters Patent, is W The combination of a waterconducting pipe, said pipe having a removable section provided with anenlarged portion forming a chamber in the pipe and said chamber havingdiametrically opposed openings, plugs screwed into said openings and oneof them having holes therethrough, and a tubular conductor for aheat-carrying medium having one section thereof disposed outside of saidpipe and mounted at its ends in said holes in the plug and anothersection thereof disposed inside of said pipe and extending throughoutsubstantially the length thereof, said lastnamed section comprising avertical loop- 1 this 10th day of February, 190 i, and JOHN shapedportion, substantially horizontal por- FRALEY this 11th day of February,1904. tions having their ends respectively mounted JOHN COLLINS. in saidholes in the plug, and elbows oonnect- JOHN FRALEY. 5 ing said portions,substantialh as described.
